    thanks, i will try these out.
    i think i might still have kjaerhus reverb on a drive somewhere, i definitely had most of the kjaerhus plugins at some point and i usually keep things like that longer than i should :)
    i will dig it out and try the others, thanks

    confirmed here too.
    i was just playing around with it and not even looking for this problem and it was very obvious when it happened. suddenly the whole thing jumped to the right.
    i narrowed it down to the early reflections section.
    it seems to be worse with certain "types" and not there at all with other types. the "airport distant" type was the worst i could find (but i didnt do any proper testing yet).
    you can re-balance it using the "early balance" control. maybe thats why they included this.

    But not a bug of Breverb It's the basic reaction of reverb when you use it in send

    interesting. was your reverb turned up here? mine was turned all the way down so i could only hear the early reflections.
    could also be that it sends certain frequencies to the right and others to the left, but is harmonic, so my sound was sent right?
    also, what version are you using?
    maybe we can share some patches too to see if we can figure out whats going on, and why some of us have the problem and others dont.

    i will do some tests and see if i can narrow my problem down

    EDIT:
    just did some very quick testing and it does appear to just be certain settings are placing the microphone off-centre in the room. some frequencies are being sent one side and others to the other side, which is how you would expect early reflections to work, its just odd that it does this by default, then lets you pan back to centre, rather than start centre and pan to taste.

    i copied your settings and mine still panned right, but not as much as in the other images i posted. when i raised my reverb knob though the meters showed the balance to be centred, so i assume your reverb was up?
    i also used s1 with the same tone gen.

    EDIT 2:
    after running some transient noise through it i can hear that my suspisions were correct, it is placing the listener off centre by default, so the centre position on the pan control is not actually the center position in the room.
    but you can use that control to correct this and re-place the listener to the centre

    i do it and yest the early on airport distant is pan on the right, after it's a choice, airport close is more center, the alley distant is center, strict distance a little bit left

    But i'm not surprise cos the breverb 2 you get the lexicon and TC electronic in 1 reverb
    and if you take the VSS3 with the airport early (rev level off)
    [​IMG]


    Breverb rev off just the early, you get the same pan (see on the master) on the early than vss3 (test venue and same too between both)
    [​IMG]

    one of the reason i use it, get 2 (lexicon, TC) in one, very light on CPU and just 0ms latency when it's 8.5ms for the vss3 (not the best for play live). And the sound is very good. And preset 1 to 4 is lexicon, the others are the TC electronic

    ah okay they are emulating old reverb units, makes a lot of sense now. i am glad they have added the pan control so you can re-centre if you need to.
    i noticed another weird thing with the band time adjust section. when you lower the low band all the way it seems to boost the next band up (feedback level). i cant recreate it with other bands. very odd. i wonder if this is another emulation.
    as great as it is for a low CPU reverb, i think i might try some more of the suggestions out and see how they compare. breverb is not really sitting very well with me now :(
    there were a lot of valhalla suggestions. i think i will try those out and revisit ones i have not used for years.

    I'm extremely sensitive on reverb, Reaper ReaVerb or Voxengo OldSkoolVerb always has been enough for me. I don't use factory presets, always build my own. I just listen to what I want to hear. Probably a Creator vs Mixer thing. Specialism.... etc...

    Sorry, I'm teaching my son and nephew lately, and all they do is preset jump and drives me crazy.

    CPU is great, I have an older i5 4th gen CPU, never has an issue. My most complex song has 94 tracks, 16 instances of reverb. I use a pan / split into 2 reverbs so 8 tracks split. Overall I don't hit high on CPU but I have to watch crap like Serum/Diva more than reverb to be honest.

    I did a bit of testing of some random reverbs I can try,
    top 3 least cpu demanding (in this order):
    1. ReaVerb (Cockos Reaper)
    2. Breverb 2 (Overloud)
    3) MConvolutionEZ (Melda)

    Out of topic ´cause they´re high on CPU but Waves Abbey Road Plates and Chambers are not from this planet. Impressive reverbs.

    Everyone? At least - their own default, init preset, for every single plugin - as a starting point, or (mix 0%, comp 0%, flat eq curve...) placing plugin from the browser in chain? In daws which 'ignore user inits/defaults', e.g. placing OTT with 100% depth on loudly monitored loud track, can be unprese(n)ted sonic experience.

    thanks
    i have MConvolutionEZ and i thought i tried it and it turned out to be much higher CPU than a lot of others tested. im not 100% sure i didnt test MConvolution instead though, i will go back and try it.

    I did just a brief test, it's very likely most of the reverb plugins will perform different depending on settings/preset applied

    agreed. i can imagine convolution plugins would perform differently depending on the impulse loaded too, so its possible i didnt experiment with different options.

    Mh, I think the pan position should remain at least a bit, on principle.

    So both are moving the ERs to the right? That's strange, isn't it?

    I made a quick Valhalla Room - Altiverb comparison some days ago and surprisingly Room was pretty close to Altiverb in terms of CPU consumption.

    The so called "cpu usage" in DAWs is the realtime cpu usage,as opposed to the cpu usage report in the task manager.So your realtime time cpu usage in your DAW may hit the 100% when in the task manager your cpu usage barely hits the 50%.
